More detailed transfer statistics

[psygarden]

Hey guys

I'm looking for some information, i'd like to find out more details about the bandwidth usage for one of my member websites. In one day, he caused 35gb of traffic instead of the normal gigabyte/day.

Now i'd like to find out a way to track what files are causing this, 1gb of it is supposed to be ftp traffic, the rest is http traffic.

It's the http traffic i'd like to focus on, is there a way to find out what urls are using most of the bandwidth? (and possible the referrers to find out where the files are being liked to from?

greetings,
Rik
